Against Heresies (Book I, Chapter 27)

Doctrines of Cerdo and Marcion.

1. Cerdo was one who took his system from the followers of Simon, and came to live at Rome in the time of Hyginus, who held the ninth place in the episcopal succession from the apostles downwards. He taught that the God proclaimed by the law and the prophets was not the Father of our Lord Jesus Christ. For the former was known, but the latter unknown; while the one also was righteous, but the other benevolent.

2. Marcion of Pontus succeeded him, and developed his doctrine. In so doing, he advanced the most daring blasphemy against Him who is proclaimed as God by the law and the prophets, declaring Him to be the author of evils, to take delight in war, to be infirm of purpose, and even to be contrary to Himself. But Jesus being derived from that father who is above the God that made the world, and coming into Judæa in the times of Pontius Pilate the governor, who was the procurator of Tiberius Cæsar, was manifested in the form of a man to those who were in Judæa, abolishing the prophets and the law, and all the works of that God who made the world, whom also he calls Cosmocrator. Besides this, he mutilates the Gospel which is according to Luke, removing all that is written respecting the generation of the Lord, and setting aside a great deal of the teaching of the Lord, in which the Lord is recorded as most dearly confessing that the Maker of this universe is His Father. He likewise persuaded his disciples that he himself was more worthy of credit than are those apostles who have handed down the Gospel to us, furnishing them not with the Gospel, but merely a fragment of it. In like manner, too, he dismembered the Epistles of Paul, removing all that is said by the apostle respecting that God who made the world, to the effect that He is the Father of our Lord Jesus Christ, and also those passages from the prophetical writings which the apostle quotes, in order to teach us that they announced beforehand the coming of the Lord.

3. Salvation will be the attainment only of those souls which had learned his doctrine; while the body, as having been taken from the earth, is incapable of sharing in salvation. In addition to his blasphemy against God Himself, he advanced this also, truly speaking as with the mouth of the devil, and saying all things in direct opposition to the truth—that Cain, and those like him, and the Sodomites, and the Egyptians, and others like them, and, in fine, all the nations who walked in all sorts of abomination, were saved by the Lord, on His descending into Hades, and on their running unto Him, and that they welcomed Him into their kingdom. But the serpent which was in Marcion declared that Abel, and Enoch, and Noah, and those other righteous men who sprang from the patriarch Abraham, with all the prophets, and those who were pleasing to God, did not partake in salvation. For since these men, he says, knew that their God was constantly tempting them, so now they suspected that He was tempting them, and did not run to Jesus, or believe His announcement: and for this reason he declared that their souls remained in Hades.

4. But since this man is the only one who has dared openly to mutilate the Scriptures, and unblushingly above all others to inveigh against God, I purpose specially to refute him, convicting him out of his own writings; and, with the help of God, I shall overthrow him out of those discourses of the Lord and the apostles, which are of authority with him, and of which he makes use. At present, however, I have simply been led to mention him, that you might know that all those who in any way corrupt the truth, and injuriously affect the preaching of the Church, are the disciples and successors of Simon Magus of Samaria. Although they do not confess the name of their master, in order all the more to seduce others, yet they do teach his doctrines. They set forth, indeed, the name of Christ Jesus as a sort of lure, but in various ways they introduce the impieties of Simon; and thus they destroy multitudes, wickedly disseminating their own doctrines by the use of a good name, and, through means of its sweetness and beauty, extending to their hearers the bitter and malignant poison of the serpent, the great author of apostasy. Revelation 12:9.
